SA Detailed Gravity Survey 92B3 (P199273), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This SA Detailed Gravity Survey 92B3 (P199273) contains a total of 139 point data values acquired at a spacing of 500 metres. The data is located in SA and were acquired in 1992, under project No. 199273 for None.

重力数据用于观测地球表层下方岩石密度变化所引发的微小重力场变化。所采集的数据将通过标准方法进行处理，以确保记录得到的重力响应仅由地下岩石引起。经处理得到的数据集可通过解译，用以揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量核验，以确保GA发布的最终数据满足使用要求。本次南澳大利亚州（South Australia，简称SA）详细重力测量92B3（编号P199273）共包含139组测点数据，测点间距为500米。本次测量数据采集于南澳地区，完成于1992年，隶属于编号为199273的项目，无明确委托方。
